[Measuring blood flow and catheterization technic in the acute and chronic dog model].

Metabolic studies under in vivo conditions may require a simultaneous catheterization of various organs. Because of phylogenetic relationships, pigs or dogs are best suitable for metabolic investigations. Organ-specific flow rates and substrate balances can be determined by means of dye dilution techniques (indocyanine green - ICG, para-aminohippuric acid - PAH, bromsulphthalein - BSP). An easy method for catheter insertion under anesthesiological and operative conditions is described.
